[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-5 As shown in the figure, a protective railing for civil construction provided by this utility model includes a post 1, a support component 2 installed at the bottom of the post 1, the support component 2 being placed on the ground, and the support component 2 being used at least to maintain the stability of the post 1; a ball joint connector 3 is provided at the top of the post 1, and a protective net 4 is provided between adjacent ball joint connectors 3; a plurality of vertically distributed railings 5 ​​are provided between adjacent posts 1, and a rotating joint 6 is provided in the middle of the railing 5, the rotating joint 6 being used at least for bending the railing 5.

[0035] In this embodiment, column 1 is included;

[0036] Specifically, a passageway 11 is provided in the middle of the column 1, and the railing 5 is inserted into the interior of the passageway 11;

[0037] Specifically, a number of positioning holes 12 are provided on the side wall of the column 1. The positioning holes 12 and bolts are used to fix the railing 5 inside the column 1. By inserting the bolts into the positioning holes 12, the railing 5 inside the passageway 11 is fixedly installed on the column 1.

[0038] Specifically, a connecting platform 13 is fixedly installed at the bottom of the column 1. The connecting platform 13 is a boss structure that is smaller at the top and larger at the bottom, so as to realize the fixed connection between the base 21 and the column 1.

[0039] In this embodiment, a support component 2 is installed at the bottom of the column 1. The support component 2 is placed on the ground and is used at least to maintain the stability of the column 1.

[0040] Specifically, the support component 2 includes a base 21, which is a hollow structure. A water inlet 22 is provided on one side of the top of the base 21. Water can be injected into the interior of the base 21 through the water inlet 22, thereby increasing the weight of the base 21 and achieving stable support for the column 1. The base 21 can be placed on a flat ground for use.

[0041] Specifically, the outer wall of the top of the base 21 is provided with several through holes 23. A ground cone 24 is inserted into the inside of the through hole 23. By inserting the ground cone 24 into the inside of the through hole 23 and inserting the ground cone 24 into the ground, the base 21 can be fixedly installed on the ground in another way, so as to achieve stable support for the column 1.

[0042] Specifically, the bottom of the ground cone 24 is pointed, which makes it easier for the ground cone 24 to be inserted into the soil;

[0043] Specifically, the top of the ground cone 24 is equipped with an impact head 25, which can be used to strike the impact head 25 with a hammer to insert the ground cone 24 into the soil.

[0044] In this embodiment, a ball-head connector 3 is provided at the top of the column 1;

[0045] Specifically, the ball head connector 3 includes a sleeve 31 that is fitted onto the outside of the top of the column 1. Fitting the sleeve 31 onto the top of the column 1 can reinforce the top of the column 1. A ball head 32 is fixedly installed at the top of the sleeve 31. The ball head 32 improves the aesthetics of the guardrail. Hooks 33 are provided on both outer walls of the ball head 32. The hooks 33 can be used to achieve a fixed connection with the protective net 4.

[0046] In this embodiment, a protective net 4 is provided between adjacent ball head connectors 3;

[0047] Specifically, the protective net 4 is woven from several weft ropes 41 and warp ropes 42. The bottom end of the warp rope 42 located in the middle of the protective net 4 is provided with a fixed rope head 43. The fixed rope head 43 is fixed to the ground. Ground nails can be set on the ground to fix the fixed rope head 43 to the ground nails, thereby realizing the fixed installation of the protective net 4.

[0048] In this embodiment, several vertically distributed retaining rods 5 are provided between adjacent columns 1. The retaining rods 5 can be arranged in a three-layer structure to form a protective structure with the columns 1.

[0049] In this embodiment, a rotating joint 6 is provided in the middle of the retaining rod 5, and the rotating joint 6 is used for bending the retaining rod 5 at least.

[0050] Specifically, the rotating joint 6 includes a first restraint sleeve 61 fixed to one end of a rod 5 and a second restraint sleeve 62 fixed to one end of another rod 5.

[0051] Specifically, positioning core 2 64 and positioning core 1 63 are respectively inserted into the interior of the first binding sleeve 61 and the second binding sleeve 62. Positioning core 2 64 and positioning core 1 63 can slide up and down inside the first binding sleeve 61 and the second binding sleeve 62, but cannot rotate inside the first binding sleeve 61 and the second binding sleeve 62.

[0052] Specifically, both the ends of positioning core 2 64 and positioning core 1 63 are provided with guide rings 65, and both the outer walls of positioning core 2 64 and positioning core 1 63 are provided with several protruding ribs 66. Positioning core 2 64 and positioning core 1 63 are inserted into the interior of restraint sleeve 1 61 and restraint sleeve 2 62 through the protruding ribs 66.

[0053] Specifically, friction surfaces 67 are provided on the outer walls of the opposite side of positioning core 2 64 and positioning core 1 63. When positioning core 2 64 and positioning core 1 63 are in contact, the friction surfaces 67 are used to lock the rotation between positioning core 2 64 and positioning core 1 63, thereby making the two side rails 5 form a relatively fixed structure.

[0054] Specifically, a nut sleeve 68 is fixedly installed inside the bottom end of the second restraint sleeve 62, and a pre-tightening bolt 69 is inserted into the inside of the guide ring 65. The nut of the pre-tightening bolt 69 is engaged inside the nut sleeve 68, and a retaining ring is provided on the top of the pre-tightening bolt 69. The operator can rotate the pre-tightening bolt 69 by holding the retaining ring. The pre-tightening bolt 69 is used to fix and lock the positioning core 2 64 and positioning core 1 63. When adjusting the side rails 5, the pre-tightening bolt 69 is loosened, so that the positioning core 2 64 and positioning core 1 63 can rotate relative to each other. After adjusting the angle of the side rails 5, the pre-tightening bolt 69 is used to lock the positioning core 2 64 and positioning core 1 63, thereby fixing the side rails 5 and forming a protective fence structure around the shape of the construction site. This effectively improves the utilization rate of the protective fence and reduces the surplus use of the protective fence.

[0055] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
